getOversampleFactor

public final double getOversampleFactor()

Return the oversampleFactor. When sampling, we would collect that much more
results, so that later, when selecting top out of these, chances are higher
to get actual best results. Note that having this value larger than 1 only
makes sense when using a SampleFixer which finds accurate results, such as
TakmiSampleFixer. When this value is smaller than 1, it is
ignored and no oversampling takes place.
